Abstract
In the current scenario, many natural fibers available in the world can be used in various applications in the day-to-day life of biomedical products, automobile parts, industrial products, etc. Biocomposites can replace or serve as a framework allowing the regeneration of traumatized, degenerated tissues, and organs, thus, improving the patients’ quality of life. This research work is aimed at fabricating and investigating the natural biopolymer composites for biomedical applications. There are two sets of fiber composites fabricated in this research work. Ramie fiber considers a common base fiber for both composites. Hemp fibers and coir fibers were considered as filler in this research work. Biodegradable and bioresorbable polypropylene resins are used to fabricate the biocomposite using the compression moulding technique. Different proportion specimen mechanical properties were compared for bone fixtures and joint applications. The contour plots and bar charts were plotted to identify the variations in the volume percentage. The individual fiber specimens also have significant properties when compared with the composite fibers. Then, the individual superior property-based combinations such as hemp and coir fiber mixed with biodegradable and bioresorbable polypropylene/ramie fiber were recommended to produce joints and bone fixtures to alleviate pain for patients.
Highlights
Synthetic polymer and biodegradable polymers are commonly used in bioplastic production
The combination of 25% of ramie and 75% of coir fiber composite reached the maximum elongation (15.44%) and the minimum percentage of elongation (1.982%) obtained by the composite of the composite 25% of ramie and 75% of hemp fiber
The use of hemp fiber and coir fiber mixed with biodegradable and bioresorbable polypropylene/ramie fiber can produce joints and bone fixtures to alleviate pain for patients. This examination of comparison of properties on ramie fiber with hemp fiber and coir fiber composites gives the following as a comparison results (i) Both the combination of set 1 and set 2 of the fiber composite can be produced (ii) From the tensile strength analysis, the set 1 results provided the higher tensile values (704 MPa) compared to set 2 results (399.2 MPa) for the properties such as tensile strength (iii) In density analysis, set 1was registered as 1.54 g/cm3, and set 2 was registered as 1.458 g/cm3 in Young’s modulus analysis
Summary
Synthetic polymer and biodegradable polymers are commonly used in bioplastic production. Mamtaz et al [1] give information about the composites of natural fibers through the water absorption basis with the help of various experiments. They mentioned the impact of sodium hydroxide concentration and different theoretical considerations with the number of mathematical relation equations and definitions. Van Krevelen [2] entirely explained the various details of the polymers such as natural fiber with different verities list in a clear approach. He gives details about the fiber matrix by way of interfacial bonding. He produced straightforward potentials summaries regarding numerous fibers mainly the hemp fiber
